This study assesses the significance of homogenisation models in theoretically analysing vibrations three-layered microbeams with a core composed axially functionally graded (AFG) material and upper lower face layers metal foam material, especially when third order shear deformation beam theory modified couple stress are used. The is assumed to vary following power gradation profile. range schemes, including Voigt model, Reuss Voigt-Reuss-Hill Tamura Mori-Tanaka bounds Hashin-Shtrikman,...
In this paper, a new theoretical approach is presented for modelling the free vibrations of functionally graded (FG) graphene platelets (GPL) reinforced thick beams with single-edge crack. To model crack in GPL beams, strain-displacement, strain-stress, velocity-momentum, and dynamic equilibrium equations are framework Hu-Washizu-Barr variational method, which three complex coupled motion obtained. The beam assumed to be continuous thick, shear effects considered by employing Timoshenko...
The present work investigates the coupled five-parameter dynamics, in particular, structural resonance frequency, of functionally graded (FG) graphene-platelets reinforced viscoelastic plates presence geometric and material (porosity) imperfections, based on Mindlin theory third-order shear deformation plate (TSDPT). Various imperfections are often found structures as a result challenges manufacturing operations over time. Geometric imperfection is considered FG structure by modelling an...
This article aims to investigate the dynamics of clamped-clamped porous viscoelastic double microbeams interconnected via a layer within framework modified couple stress theory (MCST). Different types porosity distributions are considered examine material imperfection effects on microbeam. A closed-cell model is employed variation properties in thickness plane. The coupled longitudinal and lateral equations motion derived using Hamilton's principle. governing solved modal decomposition...
